U.S. researchers who followed healthy male veterans for up to 24 years found that older men who ate more high-fiber fruits were less likely to show signs of gum disease.
For more than 600 men participating in a long-running Veterans Affairs dental study, each serving of high-fiber food was linked to an almost 30 percent lower likelihood of lost teeth and a 24 percent lower risk of bone loss associated with receding gums.
The apparent benefit wasn't … full story
Loss of memory and other brain function can start as early as age 45, posing a big challenge to scientists looking for new ways to stave off dementia, researchers said.
The finding from a 10-year study of more than 7,000 British government workers contradicts previous notions that cognitive decline does not begin before 60 years of age, and it could have far-reaching implications for dementia research.
Pinpointing the age at which memory, reasoning … full story
Obese people who had weight-loss surgery were less likely to later suffer a heart attack or stroke, or to die from one, compared to people who did not have the surgery, according to a Swedish study.
The findings, published in the Journal of the American Medical Association, come from a study of more than 4,000 obese people treated at 500 surgery departments and health care centers in Sweden.
Between 1987 and 2001, half of those people opted for … full story
A large new European study finds that simply eating a lot of fruits and vegetables may not be enough to stave off the weight gain that often comes with age -- except for people who recently quit smoking.
Researchers found that of nearly 374,000 adults in 10 European countries, who were followed for five years, those who ate the most fruits and vegetables were no less likely to gain weight once other factors -- like calorie intake and exercise habits … full story
Normal weight adults, including those who had lost a lot of weight and kept it off, ate more often than overweight people in a new study looking at factors that may help in preventing weight gain.
Researchers following about 250 people for a year found that overweight individuals ate fewer snacks in addition to meals than people in the normal body weight range, but the overweight still took in more calories and they were less active over the course … full story
Australian scientists claim to have discovered a gene responsible for baldness in women which may lead to an effective treatment for hair loss.
Researchers at the University of Melbourne and St Vincent’s Hospital studied the DNA of almost 500 women who had lost at least 50 percent of hair on their scalp. Aged between 18 and 65, all the women who participated in the study, suffered severe hair loss, a condition that will affect up to 55 percent … full story
Seniors who take aspirin daily are twice as likely to have late stage macular degeneration, an age-related loss of vision, than people who never take the pain reliever, a new European study reports.
The data do not show that aspirin causes vision loss. But the findings are of concern if aspirin somehow exacerbates the eye disorder, researchers say, given how many seniors take it daily for heart disease. (Reuters)
Adults referred to the commercial weight loss programme Weight Watchers shed twice as much weight as people who received standard care over a 12-month period, according to a study published Thursday.
In clinical trials, researchers led by Susan Jebb of the UK Medical Research Council assessed 772 overweight and obese adults in Australia, Germany, and Britain.
About half the patients received a year's standard care, while the other half were given … full story
Dietary protein reduces hunger and increases fullness in overweight men during weight loss programmes, a study says.
Diets “containing 18 to 35 percent of daily calorie intake from dietary protein, are associated with reductions in hunger and increased fullness throughout the day and into the evening hours,” said Heather Leidy, study author and professor in nutrition at the University of Missouri.
“In our study, the two groups ate either 25 or … full story
Long-term exposure to air pollution could damage the brain and cause depression, besides triggering learning and memory problems.
Mice tests showed that, in the long term, dirty air could cause actual physical changes to the brain which resulted in negative effects.
While other studies have looked at the impact of polluted air on heart and lungs, this is one of the first to look at the effect on the brain, said doctoral student Laura Fonken from … full story
